THREAD-CUTTER.

SPECIFIGATION formingpart of Letters Patent No. 727,867, dated May 12,1903.

Application filed August 6, 1902.

To all whom it may concern:

Be it known that. we, HERMAN A. WEHNER and JOHN J. KEUNST, citizens ofthe United States, residing at Berlin, in the county of Green Lake andState of Wisconsin, have invented certain new and useful Improvements inThread-Cutters, of which the following is a specification;

This invention aims to provide a simple and inexpensive device forcutting thread, twine, or the like, and is specially designed to be usedby bundle-wrappers, milliners, or any one having occasion to break orsever cord in any manner.

It is customary on the partof the bundlewrapper to part thewrapping-cord after securing the package by a quick jerk of the hands,the continued wear of the cord upon the fingers, however, often causingblistering or soreness of same or like inconvenience. In sewing alsomuch inconvenience is experienced in having to reach for the scissorseach time it is found necessary to sever the thread, this being done ininnumerable instances, most frequently when the thread end is too shortto enable breaking of the same with the fingers.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foredeoting the result reference is to be had to the following descriptionand drawings hereto attached.

While the essential and characteristic features of the invention aresusceptible of modificat-ion, still the preferred embodiment of theinvention is illustrated in the accompanying drawings, in which Figure 1is a perspective View of the rear base-plate, showing more particularlyhow the catch-pin and guard are secured to same. Fig. 2 is a sideelevation. Fig. 3 is a plan section on line X X of Fig. 2. Fig. 4 is afront view. Fig. 5 is a modification.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The cutter is designed in its preferred form to be applied to thegarment of the user at a point found most convenient and depending muchupon the character of work for which Serial Ne. 118,662. (No model.)

it is utilized. However, it may be secured in any suitable manner to thecounter in a store or in any place of like character in which it wouldbe a desirable acquisition for the purpose above described.

The device comprises, essentially, a base 1, a spring-guard 2,0fpeculiar construction, fastened to the base, and a'cutter or blade 3,also secured to the base. The base in its preferred form is composed ofplates-l. and 5,

soldered together: at their edges so as to constitute a hollow body. Theplate 4. is slightly convex in form, the guard 2 having itsjshanksecured by solder or like means-between the aforementioned plates .4 and5.-

plates of the base in like manner as the guard -2. The cuttingblade 3extends outwardly and upwardly from the base, the cutting edge thereofbeing spaced from and located upon the-base side of the blade. Thespringguard The shank 'of the catch-pin 6 also is secured between the 2is formed with spaced members 8 and 9,

poses desirable to have this element secured at the bottom of the base 1and having the spring members 8 and 9, extending upward, embracing theshank as in the other'form, as shown most clearly in Fig. dot thedrawings.

The convex form of the plate 4 gives a finish to the device, alsoallowing the cord to be held at any angle during the operation ofcutting same without any danger of its catching in the edges of theplate, as would be the case were the surface of the same flat. At thelower extremity of the plate 4 and integral therewith is formed thecatch 10, the same being bent in approximatelysemicircu lar form andcooperating with the catch-pin 6 in the usual manner. The catch-pin 6 isbent inward at its point, so as to prevent pricking or scratching of theflesh or tearing of goods, which often happens in the usual form of pinhaving the straight point. It

will be understood that other securing means may be substituted for thecatch-pin when it is desired that the cutter be attached to a counter orrigid support. The general shape of the base is immaterial within thecontemplation of the invention, the same being made of any shape foundbest adapted for the puposes of the invention and deemed most suitableby us and may be either plain or fanciful in general contour.

In operation the cord or that which is to be severed is held quite tautand inserted between the guard and blade at the angle formed by thecutting edge of the blade and the said guard. Slight downward pressurewill cause the guard to spring inward, and the cord is therefore given asliding movement along the edge 7 of the blade, which readily parts thesame. The principle would be substantially the same as regards themodified construction shown. It is preferred that the guard be composedof the spaced spring members and the shank members be formed of a singlepiece of material, springwire being preferred, though this is notimportant within the spirit of the invention, which is susceptible ofvarious modified forms and changes of construction of the separate partsas included within the purview of the appended claims.

Having thus described the invention, what is claimed as new is 1. In anattachment of the character described, in combination, a base comprisingfront and rear plates rigidly secured together,

a cutting-blade projected from the said base, and a spring-guardcooperating with the aforesaid blade and having its shank portionsecured between the aforesaid base-plates, substantially as described.

2. In a cutter for thread and the like, in combination, a-basecomprising front and rear plates, the front plate being approximately ofconvex form and having a catch integrally formed therewith, a bladeprojected from the front plate of the base, a springguard embracing thesides of the blade and cooperating with the cutting edge thereof toseparate the cord, and a catch-pin upon the rear side of the base,substantially as described.

3. In a thread-cutting attachment, a base comprising front and rearplates, a blade projected from the said base and cooperating with aspring-guard secured thereto, said guard comprising spaced membersembracing the sides of the blade and formed from a single strand ofspring-wire, the shank por tion of the guard being secured between theplates of the base, and means for holding the device in position,substantially as set forth.

In testimony whereof we affix our signatures in presence of twowitnesses.
